Profile

Hi HN, I built this because I kept pasting client data and API keys into ChatGPT without thinking.It detects 15+ types of PII as you type, masks them with placeholders like [PERSON_A] before sending, then unmasks the AI's response. Everything runs locally — no servers, no data collection, zero network requests. You can verify in DevTools.Built as a solo project using Claude Code.Chrome Web Store: https://chromewebstore.google.com/detail/privacyshield/nklgh...This is v0.1 — would love feedback. Bugs: support@piiblock.com or GitHub issues.

PrivacyShield – Mask your PII before it reaches ChatGPT/Claude is positioned in show hn launch, a segment that rewards a clear, focused offering.

The company is listed at the Show HN launch stage of development.
